Title: Light Echoes of Galactic Explosions and Eruptions

Abstract: We propose to continue our search for the first light echoes (LEs) associated with historical Galactic supernovae and LBV outbursts: SN~1006, Kepler's SN, RCW~86, Crab Nebula, and P~Cygni. In previously granted NOAO time, we have discovered LEs of three ancient SNe in the LMC as well as from the historic SN events of Cas~A and Tycho [2, 3], which allowed their spectroscopic classification [6, 7, 10] and 3D spectroscopy [8, 9]. Most recently, we discovered light echoes of the mid-19th-century Great Eruption of $\eta$~Carinae using CTIO 4m Mosaic images [11]. We propose to continue our search for light echoes of the remaining historical events. With DECam, we have a 10-15 fold improvement in efficiency over the retired CTIO-Mosaic camera, which allows us to cover the bigger search areas of most of the remaining targets. With the KPNO 4-m, we will observe fields too far north for CTIO/DECam. The study of scattered-light echoes from these Galactic supernovae and eruptions will give us the opportunity to directly compare the original outburst and its current remnant, and in favorable cases (like Eta~Carinae), it provides a three-dimensional view of the event and/or a spectral time series.
